M-MATE (Measuring Machine for the Angular Transmission Error) is the systems which measure the performance of gears including the angular transmission error (ATE). The Performance of M-MATE is changed by the selection of parts. It is possible that the System accuracy of ATE is less than ±2arc-sec or the measuring rotational speed of the input shaft is more than 1000rpm. M-MATE can measure not only ATE but also the rotational fluctuation generated by gears, backlash and shaft torque simultaneously. *1 [arc-sec]=1/3600[deg]=4.85 [μrad]
